The only method I can get to that page is by using beta.litespeedtech.com , not www.litespeedtech.com , you may want to make a note of this or create a redirect. www just says page not found, whereas beta sends me to the correct page. I have to use the same method to view the wiki as well.

Okay the problem is that your ISP's DNS server records has not yet been updated likely due to it not respecting our TTL. You should no longer have this problem at the end of today. Just give them a few more hours.
